Western, and many other, agricultural systems rely on huge fossil fuel inputs for fertilizer, and for the pesticides used. When energy inputs are around ten times the food energy out, claiming this as being efficient is stretching things a bit.

Efficiency can be measured in many ways and the way chemical practitioners choose to define it is by manpower: chemical farming being the most efficient way of using manpower to produce food. Chemical farming is also the most efficient in terms of cost, providing you ignore all the negatives from an environmental point of view, so is most cost efficient. It is also the most efficient way of turning oil into food, none of which definitions are very sustainable._________________As Steve Keen puts it: “Capital without energy is a statue; labour without energy is a corpse.” Economics ignores this which is why economics is broken.

I'd read such with a large salt shaker handy. They are growing corn for five dollars a bushel at a profit so that means the energy tied up in fertilizers, fuel and pesticides amounts to less then $2.50 per bushel.

There are probably a lot of subsidies hiding behind those numbers. Even in the supposedly-free-trade USA _________________Soyez réaliste. Demandez l'impossible.
